Question

Derivada de f(x)=8x^4

Answer 1

${y=8x^4}\\\\{y`=(8x^4)`}\\\\{y`=8(x^4)`}\\\\{y`=8(4x^{4-1})}\\\\{y`=8(4x^3)}\\\\{y`=32x^3}\\\\{\mathbf{salu2.!!\ :)}}\\{\mathbf{Wellington}}$

Answer 2

La fórmula a usar es  d( x ^n ) / dx = n x ^n-1, entonces se tiene:


d [ f(x) ]       8   d ( x ^4 ) 
----------- =       ------------ = 8 (4 x^4-1) = 32 x^3
    dx                    dx
